YouTube star Caspar Lee's surprise rendition of Deck The Halls is sure to get you in the festive spirit

YouTube star Caspar Lee has nearly seven million subscribers but took to the streets of London to bring a special piece of festive entertainment to a slightly smaller crowd - with an impromptu and unique cover of a Christmas classic.

The 22-year-old, armed with a triangle and flanked by some talented friends, gave a very 21st century take on Deck The Halls, featuring beat boxing and an a cappella "drop".
